In this whiteboard-style episode, we dive deep into the auditory brainstem response (ABR) and its profound implications for the autistic phenotype, tracing sound from the cochlea's powerful endocochlear potential through multi-step brainstem relays to the thalamus and auditory cortex. Highlighting high excitation paired with low inhibition, we map how poor filtering at key stations—like the superior olivary complex, lemniscus, and inferior colliculus—leads to listening dissonance, where sounds blend uncontrollably into overwhelming noise. The discussion underscores the mesencephalon's critical role in sensory gating, binaural processing, and the tr ...
